Question

Sketch the Lewis structure of the chemical compounds below. a) H2CO3 b) NaCℓ c) CaCℓ2 d) NaOH e) Ba (OH) 2

Answer 1

Explanation:

The expected products are water and barium nitrate, so the initial chemical reaction is

HNO3(aq) + Ba(OH)2(aq) → H2O(ℓ) + Ba(NO3)2(aq)

To balance the equation, we need to realize that there will be two H2O molecules, so two HNO3 molecules are required:

2HNO3(aq) + Ba(OH)2(aq) → 2H2O(ℓ) + Ba(NO3)2(aq)

This chemical equation is now balanced.
